GENERAL PROVISIONS 2.01 Engineer's Status and Authority. It is mutually agreed by and between the parties to this Contract that the Engineer shall have general supervision and direction of the work included herein. In order to prevent delays and disputes and to discourage litiga- tion it is further agreed by and between the parties of this Contract that the Engineer shall in all cases determine the amounts and quantities of the several kinds of work which are to be paid for under the Con- tract; that he shall determine all questions in rela- tion to said work and the construction thereof, that he shall in all cases decide every question which may arise relative to the execution of the Contract on the part of the Contractor; that his decisions and find- ings shall be the conditions precedent to the right of the parties hereto to arbitration or to any action on the Contract and to the rights of the Contractor to receive any money under this Contract; provided, how- ever, that should the Engineer render any decision or give any direction which in the opinion of either party hereto is not in accordance with the meaning and intent of this Contract, either party may file with the Engineer within 30 days a written objection to the decision or direction so rendered. It is the intent of this Agreement that there shall be no delay in the execution of the work, and the decision or directions of the Engineer as rendered shall be promptly carried out. 2.02 Right of Engineer to Modify Methods and Equipment. If at any time the methods or equipment used by the Con- tractor are found to be unsafe or inadequate to secure the quality of the work or the rate of progress re- quired under this Contract, the Engineer may direct the Contractor in writing to increase their safety or improve their character and efficiency and to cease operations under this Contract until such direction is complied with. No claims shall be made against the Owner for damages caused by any delay resulting from such order. -3- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2.03 Changes and Alterations. The Contractor agrees that the Owner, through the Engineer, may make such changes and alterations as the Owner may see fit in the line, grade, form, dimensions, plans, or materials for the work herein contemplated or any part thereof either before or after the beginning of the construction without affecting the validity of this Contract and the accompanying bonds. If such changes or altera- tions diminish the quantity of the work to be done, they shall not constitute the basis for a claim for damages or anticipated profits on the work that may be dispensed with. If they increase the amount of work and the increased work can fairly be classified under the specifications, such increase shall be paid for according to the quantity actually done and at the unit price established for such work under this Con- tract; otherwise such work shall be paid for as pro- vided under Section 2.12 "Extra Work ". In the event the Owner shall make such changes or alterations which will make useless any work already done or material already furnished or used in said work, then the Owner shall compensate the Contractor for any materials or labor so used, for any actual loss occasioned by such change, and for the actual expenses incurred in prepa- ration for the work as originally planned. 2.04 Damages. The right of general supervision by the Owner shall not make the Contractor an agent of the Owner, and the liability of the Contractor for all damages to persons, firms, and corporations arising from the Contractor's execution of the work shall not be lessened because of such general supervision. The Contractor is an independent contractor in regard to work under this Contract, and as such is solely liable for all damages to any persons, firms, corporations, or their property as a result of the prosecution of the work. 2.05 Losses from Natural Causes. All loss or damage aris- ing out of the nature of the work to be done or from the action of the elements or from any unforeseen cir- cumstances in the prosecution of the work or from unu- sual obstructions or difficulties which may be encoun- tered in the prosecution of the work shall be sustain- ed and borne by the Contractor at his own cost and expense. 2.06 Laws and Ordinances. The Contractor shall at all times observe and comply with all Federal, State, and local laws, ordinances, rules and regulations which -4- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 in any manner affect the Contract or the work and shall indemnify and save harmless the Owner against any claim arising from the violation of any such laws and ordinances whether by the Contractor or his em- ployees or his subcontractors and their employees. 2.07 Licenses, Permits and Certificates. Except as herein- after stipulated, all licenses, permits, certificates, etc. required for and in connection with the work to be performed under the provisions of these Contract Documents shall be secured by the Contractor at his own expense. In the event a building permit is re- quired such permit will be obtained by the Owner at no cost to the Contractor. 2.08 Royalties and Patents. The Contractor shall protect and save harmless the Owner from all and every demand for damages, royalties, or fees on any patented inven- tion used by him in connection with the work done or material furnished under this Contract; provided, how- ever, that if any patented material, machinery, appli- ance, or invention is clearly specified in this Con- tract, the cost of procuring the rights of use and the legal release or indemnity shall be borne and paid by the Owner direct unless such cost is determined and directed to be included in the bid price at the time the Proposal is submitted. 2.09 Reeving of Plans and Specifications Accessible. The Engineer shall furnish the Contractor with three (3) sets of executed Plans and Specifications without ex- pense to him, and the Contractor shall keep one copy of the same constantly accessible on the work, with the latest revisions noted thereon. 2.10 Discrepancies and Omissions. It is further agreed that it is the intent of this Contract that all work must be done and all material must be furnished in ac- cordance with the generally accepted practice, and in the event of any discrepancies between the separate contract documents, the priority of interpretation de- fined under "Contract Documents" shall govern. In the event that there is still any doubt as to the meaning and intent of any portion of the Contract, Specifica- tions or -Drawings, the Engineer shall define which is intended to apply to the work. 2.11 Contractor's Understanding. It is understood and agreed that the Contractor has, by careful examina- tion, satisfied himself as to the nature and location -5- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 of the work, the conformation of the ground, the char- acter, quality and quantity of the materials to be en- countered, the character of equipment and facilities needed preliminary to and during the prosecution of the work, the general and local conditions, and all other matters which can in any way affect the work under this Contract. No verbal agreement or conversa- tion with any officer, agent, or employee of the Own- er, either before or after the execution of this Con- tract, shall affect or modify any of the terms or ob- ligations herein contained. 2.12 Extra Work. The term "extra work" as used in this Contract shall be understood to mean and include all work that may be required by the Owner through the Engineer to be done by the Contractor to accomplish any change, alteration, or addition to the work shown by the Plans or reasonably implied by the Specifica- tions and not covered by the Contractor's Proposal, except as provided in Section 2.03 - "Changes and Alterations ". it is agreed that the Contractor shall perform all extra work under the direction of the Engineer when presented with a written Change Order signed by the Engineer. No claim for extra work of any kind will be allowed unless ordered in writing by the Engineer. In case any orders or instructions, either oral or written, appear to the Contractor to involve extra work for which he should receive compensation, he shall make a written request to the Engineer for a written Change Order authorizing such extra work. Should a difference of opinion arise as to what does or does not constitute extra work or concerning the payment therefor and the Engineer insists upon its performance, the Contractor shall proceed with the work after making a written request for a written Change Order and shall keep an accurate account of the "actual field cost" thereof as provided under Method "C" below. 2.13 Payment for Extra Work. It is agreed that the compen- sation to be paid the Contractor for performing extra work shall be determined by one or more of the follow- ing methods: Method "A" - By agreed unit prices; Method "B" - By agreed lump sum; or -6- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Method "C" - If neither Method "A" or Method "B" can be agreed upon before the extra work is commenced, then the Contractor shall be paid the "actual field cost" of the work plus 15%. Where extra work is performed under Method "C ", the term "actual field cost" of such extra work is hereby defined to be and shall include: (a) the payroll cost for all workmen, such as foreman, mechanics, crafts- men, and laborers; (b) the cost of all materials and supplies not furnished by the Owner; (c) rental for all power - driven equipment at agreed -upon rates for the time actually employed or used in the performance of the extra work; (d) transportation charges neces- sarily incurred in connection with any equipment authorized by the Engineer for use on said extra work and which is not already on the job; (e) all power, fuel, lubricants, water, and similar operating expens- es; (f) all incidental expenses incurred as a direct result of such extra work including sales or use taxes on materials, payroll taxes, and the additional pre- miums for construction bonds, workmen's compensation, public liability and property damage, and other insur- ance required by the Contract where the premiums therefor are based on payroll and material costs. The Engineer may direct the form in which accounts of the "actual field costs" shall be kept and may also speci- fy in writing before the work commences the method of doing the work and the type and kind of machinery and equipment to be used; otherwise these matters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machinery and equip- ment shall be incorporated in the written extra work Change Order. The 15% of the "actual field cost" to be paid the Contractor shall cover and compensate him for his profit, overhead, and general superinten- dence. 2.14 Assignment and Subletting. The Contractor shall not assign or sublet the work or any part thereof without the previous written consent of the Owner, nor shall he assign, by power of attorney or otherwise, any of the money payable under this Contract unless by and with the consent of the Owner to be signified in like manner. If the Contractor assigns all or any part of any monies due or to become due under this Contract, the instrument of assignment shall contain a clause substantially to the effect that it is agreed that the right of the assignee in and to any monies due or to -7- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 become due to the Contractor shall be subject to all prior liens of all persons, firms, and corporations for services rendered or materials supplied for the performance of the work called for in this Contract. 2.15 Subcontractors. The Contractor shall be as fully re- sponsible to the Owner for the acts and omissions of his subcontractors and of persons either directly or indirectly employed by them as he is for the acts and omissions of persons directly employed by him. Should any subcontractor fail to perform the work undertaken by him in a satisfactory manner, his subcontract shall be immediately terminated by the Contractor upon writ- ten notice from the Owner. 2.16 Owner's Status. Nothing contained in this Contract shall create any contractual relation between any sub- contractor and the Owner. 2.17 Completed Portions of Work. The Owner shall have the right to take possession of and to use any completed or partially completed portions of the work prior to completion of the entire work, but such use shall not constitute an acceptance of any of the work not com- pleted in accordance with the Contract Documents. If the Engineer determines that taking possession of and using partially completed work substantially increases the cost of or delays construction, the Contractor shall be entitled to extra compensation or extension of time or both as determined by the Engineer. 2.18 Materials. All materials furnished by the Contractor s all be as required by the Plans and Specifications or as otherwise stipulated. The Contractor shall not start delivery of materials which he is to furnish until the Engineer has approved the source of supply of such materials. 2.19 Receiving and Storage of Materials. The Contractor shall make arrangements for receiving and storing materials. The Owner will not sign for or receive shipments of materials consigned to the Contractor.

The Engineer will evaluate the request to determine if the material, product, or article is of equal substance and function and if it will perform identically the duties imposed by the general design. Written approval of an "or equal" material, product, or article must be obtained from the Engineer before it may be incorporated into the work as a substitute for that specified in the Con- tract Documents. 2.21 Completed Work. The Contractor shall maintain contin- uous adequate safeguards to protect all completed work from damage, loss, or the intrusion of foreign ele- ments. 2.22 Materials Furnished by the Owner.

The Contractor shall give reasonable notice to the owner or owners of public or private property and utilities when such property is liable to injury or damage through the performance of the work, and he shall make all necessary arrangements with such owner or owners relative to the removal and replacement or protection of such property or utili- ties. The Contractor shall satisfactorily shore, support, and protect any and all structures, and all pipes, sewers, drains, conduits, and other facilities belong- ing to the Owner, and he shall be responsible for any damage resulting thereto. The Contractor shall not be entitled to any damages or extra pay as a result of any postponement, interference, or delay caused by any such structures and facilities being on the line of the work whether they are shown on the Plans or not. 2.24 Shelters for Workmen and Materials. The building or structures for housing men or the erection of tents or other forms of protection for workmen or materials will be permitted only as the Engineer shall authorize or direct. The sanitary conditions of the grounds in or about such structures shall at all times be main- tained in a manner satisfactory to the Engineer. -9- 1 1 1 1 1 1 1 1 r 1 1 1 1 1 1 1 1 1 1 2.25 Sanitary Facilities.

In the event that the Contractor and the superinten- dent are both absent from the site of the work for prolonged periods of time the Engineer may order any or all work under this Contract to be stopped until the Contractor provides continuous and proper supervi- sion of the work. Such stoppage shall not constitute a basis for any claim against the Owner for damages caused by delay for such work stoppages. 3.05 Character of Employees. The Contractor agrees to em- ploy only order y, competent, and skillful persons to do the work, and whenever the Engineer shall inform him that the work being accomplished is of sub -stan- dard character by reason of carelessness, incompe- tence, or inexperience on the part of the workers the installation of such work shall be immediately sus- pended and shall not be resumed until the Engineer is satisfied that the conditions causing such faulty work have been corrected. 3.06 Contractor's Duty to Protect Persons and Property. In the performance of this Contract, the Contractor shall protect the public and the Owner fully by taking rea- sonable precaution to safeguard persons from death or bodily injury and to safeguard property of any nature whatsoever from damage.

The duties of the Contractor in this paragraph shall be nondeleg- able, and the Contractor's compliance with the speci- fic recommendations and requirements of the Owner as to the means of warning shall not excuse the Contrac- tor from the faithful performance of these duties should such recommendations and requirements not be adequate or reasonable under the circumstances. 3.07 Safety Codes. The Contractor shall comply with all applicable provisions of any Federal, State, and Muni- cipal safety laws and building and construction codes.

Should the Contractor fail to initiate compliance with the above provision within 72 hours or should he fail to properly prosecute and complete correction of such faulty work, the Engineer may direct that the work be done by others and that the cost of the work be de- ducted from monies due the Contractor. 3.11 No Waiver of Contractor's Obligations. The Engineer, supervisor, or inspector shall have no power to waive the obligations of this Contract for the furnishing by the Contractor of good material and of his performing good work as herein described and in full accordance with the plans and specifications. No failure or omission of the Engineer, supervisor, or inspector to condemn any defective work or material shall release the Contractor from the obligation to at once tear out, remove, and properly replace the same at any time prior to final acceptance upon the discovery of said defective work or material; provided, however that the Engineer, supervisor, or inspector shall upon request of the Contractor inspect and accept or reject any material furnished, and once the material has been ac- cepted by the Engineer, supervisor, or inspector such acceptance shall be binding on the Owner unless it can be clearly shown that such material furnished was not as represented and does not meet the specifications for the work. Any questioned work may be ordered taken up or removed for re- examination by the Engineer prior to final acceptance, and if found not in accor- dance with the specifications for said work, all ex- pense of removing, re- examination, and replacement shall be borne by the Contractor; otherwise the ex- pense thus incurred shall be allowed as "Extra Work" and shall be paid for by the Owner. 3.12 Site Clean Up.

During a period of 12 months from and after the date of the final acceptance by the Owner of the work embraced by this Contract, the Contractor shall make all needed repairs arising out of defective workmanship or materials, or both, which in the judg- ment of the Owner shall become necessary during such period. If within 10 days after the mailing of a notice in writing to the Contractor or his agent the said Contractor shall neglect to make or to undertake with due diligence the aforesaid repairs, the Owner is hereby authorized to make such repairs at the Contrac- tor's expense; provided, however, that in case of an emergency where, in the judgment of the Owner, delay would cause serious loss or damage, repairs may be made without notice being sent to the Contractor, and the Contractor shall pay the cost thereof. 4. OWNER'S OBLIGATIONS AND RESPONSIBILITIES 4.01 Lines and Grades. All necessary lines and grades shall be furnished by the Engineer. Whenever neces- sary, work shall be suspended to permit performance of this work, but such suspension will be as brief as practicable, and the Contractor shall be allowed no extra compensation therefor.

The respective rights of and operations of the various interests involved shall be established and coordinated by the Engineer. 4.05 Right -of -Way. Easements across private property and lands needed for construction under this Contract will be provided by the Owner. 4.06 Adequacy of Design. It is agreed that the Owner shall be responsible for the adequacy of the design, suffi- ciency of the Contract Documents, the safety of the structure and practicability of the operations of the completed project; provided the Contractor has com- plied with the requirements of the said Contract Docu- ments, all approved modifications thereof, and addi- tions and alterations thereto approved in writing by the Owner. The burden of proof of such compliance shall be upon the Contractor to show that he has com- plied with the said requirements of the Contract Docu- ments, approved modifications thereof and all approved additions and alterations thereto. 5. SCHEDULING AND PROGRESS OF WORK 5.01 Order and Prosecution of the Work. It is the meaning and intent of this Contract, unless otherwise herein specifically provided, that the Contractor shall be allowed to prosecute his work at such times and sea- sons in such order of precedence and in such manner as shall be most conducive to economy of construction; -15- provided however, that the order and time of prosecu- tion shall be such that the work shall be substantial- ly completed as a whole or in part in accordance with this Contract within the time of completion hereafter designated; provided also that the Engineer may direct the time and manner of constructing any part or parts of the work when in his opinion such should be given priority to lessen the probability of danger to the public or to anticipate seasonal hazards from the ele- ments or to coordinate with other work being done for or by the Owner. 5.02 Rate of Progress. The Contractor shall give the Engi- neer full information in advance as to his plans for carrying on any part of the work. If at any time prior to the start or during the progress of the work any part of the Contractor's plant or equipment or any of his methods of executing the work appear to the Engineer to be unsafe, inefficient, or inadequate to insure the required quality or rate of progress of the work, the Engineer may order the Contractor to in- crease or improve his facilities or methods, and the Contractor shall promptly comply with such orders; but neither compliance with such orders nor failure of the Engineer to issue such orders shall relieve the Con- tractor from his obligation to secure the degree of safety, the quality of work, and the rate of progress required by this Contractor. The Contractor alone shall be responsible for the safety, adequacy, and efficiency of his plant, equipment, and methods. 5.03 Sunday, Holiday, and Night Work. Except in connection with the care, maintenance, or protection of equipment or of work already done, no work shall be done between the hours of 6:00 p.m. and 7:00 a.m. or on Sundays or legal holidays without written consent of the Engi- neer. 5.04 Hindrances and Delays. No claims shall be made by the Contractor for damages, hindrances, or delays from any cause during the progress of any portion of the work embraced by this Contract except where the work is stopped by order of the Owner. If the Owner stops the work for just cause because the Contractor is not com- plying with the plans and specifications or the intent thereof, the Contractor shall have no claim for dam- ages, hindrances, or delays. However, if the Owner stops the work for any other reason, the Contractor shall be entitled to reimbursement paid by the Owner for such expenses actually incurred which in the judg- ment of the Engineer occurred as a result of the work stoppage. -16- Should delays repeatedly occur due to the Contractor's failure to provide adequate plant, equipment, or per- sonnel, or where the Engineer determines that unrea- sonable inconvenience to the public is due to such failure, the Contractor's operations shall be suspend- ed until he shall have provided adequate plant, equip- ment, and personnel to properly resume and continually prosecute the work. 5.05 Extensions of Time. Should the Contractor be delayed in the final completion of the work by any act or neg- lect of the Owner or Engineer, or of any employee of either, or by any other contractor employed by the Owner, or by strikes, fire or other cause or causes outside of and beyond the control of the Contractor and which the Engineer determines could have been neither anticipated nor avoided, then an extension of time sufficient to compensate for the delay as deter- mined by the Engineer shall be granted by the Owner; provided, however, that the Contractor shall give the Owner prompt notice in writing of the cause of delay in each case. Extensions of time will not be granted for delays caused by unfavorable weather, unsuitable ground conditions or inadequate construction force. 5.06 Liquidated Damages for Failure to Complete on Time. The Contractor agrees that time is of the essence of this Contract and that the definite value of damages which would result from delay would be incapable of ascertainment and uncertain, so that for each day of delay beyond the number of days herein agreed upon for the completion of the work herein specified and con- tracted for, after due allowance for such extension of time as is provided for under the provisions of the preceding paragraph, the Owner may withhold permanent- ly from the Contractor's total compensation, not as a penalty but as liquidated damages, the sum per day given in the following schedule: Amount of Liquidated Amount of Contract Damages Per Day Less than $ 5,000.00 $ 5,001.00 to $ 15,000.00 15,001.00 to 25,000.00 25,001.00 to 50,000.00 50,001.00 to 100,000.00 100,001.00 to 500,000.00 500,001.00 to 1,000,000.00 1,000,001.00 to 2,000,000.00 2,000,001.00 to 5,000,000.00 -17- $ 30.00 35.00 40.00 50.00 70.00 200.00 300.00 400.00 500.00 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 6. INDEMNITY 6.01 Contractor's Indemnity Provision. To protect the Owner from the Contractor's failure to perform any of the foregoing duties or any of the terms of this Con- tract, the Contractor shall indemnity and save harm- less the Owner and the Owner's agents and employees from all losses, damages, judgments, decrees, and ex- penses or costs of any nature whatsoever arising out of or in anyway connected with any claims or actions at law or in equity brought against the Owner and the Owner's agents and employees for the death or injury to persons or for damage to property caused, or alleg- edly caused, by any willful acts, negligence, nui- sance, or breach of any term or condition of this Con- tract by the Contractor, his agents, servants, subcon- tractors, or employees. The Contractor shall further- more indemnify and save harmless the Owner and the Owner's agents and employees from all demands of sub- contractors, workers, material persons, or suppliers of machinery and parts thereof, equipment, power tools, and supplies incurred in connection with work to be performed under this Contract. Property of any description, including property of the Owner, which shall be damaged in the performance of this Contract by the Contractor, his agents, employees, subcontrac- tors or their employees and subcontractors shall be restored to its condition prior to damage by the Con- tractor at the Contractor's expense. 6.02 Workmen's Compensation Insurance. The Contractor agrees to comply with the Workmen's Compensation Act of the State of Texas, and to pay or cause to be paid all compensation, medical or other benefits, which may become due or payable thereunder, and to protect and indemnify the Owner and the Owner's agents and employ- ees from and against any and all liabilities by reason of accidental injury, disease or death sustained by subcontractor's employees. The Contractor shall fur- nish the Owner with a certificate from the Industrial Accident Board evidencing the Contractor's and subcon- tractors' compliance with said statute. 6.03 Comprehensive General Liability Insurance. The Con- tractor shall provide and maintain during the life of this Contract and until all work under said Contract has been completed and accepted by the Owner, a Com- prehensive General Liability insurance policy, said policy and the issuing carrier approved by the Owner, which specifically insures the contractual liability -18- of the Contractor assumed under Paragraph 6.01 above entitled "Contractor's Indemnity Provision ". The lia- bility coverage under this policy shall cover Indepen- dent Contractors. Liability limits for the Comprehen- sive General Liability insurance coverage under this policy shall not be less than the following: Bodily Injury $100,000 each person $300,000 each accident Property Damage $ 25,000 each accident $ 50,000 aggregate 6.04 Owner's Protective Insurance. The Contractor shall provide and maintain during the life of this Contract and until all work under said Contract has been com- pleted and accepted by the Owner, an Owner's and Con- tractor's Protective Policy which co- insures the Owner and the Owner's agents and employees with the same Comprehensive General Liability coverage as described in 6.03 above entitled "Comprehensive General Liabil- ity Insurance ". 6.05 Comprehensive Automobile Liability Insurance. The Contractor shall provide and maintain during the life of this Contract and until all work under said Con- tract has been completed and accepted by the Owner, a Comprehensive Automobile Liability insurance policy, said policy and issuing carrier approved by the Owner, covering the operation on or off the site of the work of all motor vehicles licensed for highway use, whe- ther they are owned, non - owned, or hired by the Con- tractor, in which shall specifically insure contrac- tual liability of the Contractor assumed under the above Paragraph 6.01 entitled "Contractor's Indemnity Provision ". The liability limits for the Comprehen- sive Automobile Liability insurance coverage shall not be less than the following: Bodily Injury $100,000 each person $300,000 each accident Property Damage $ 50,000 each accident 6.06 Insurance Certificate. In connection with the insur- ance coverage set out in sections 6.02, 6.03, 6.04, and 6.05 above, the Contractor shall furnish the Owner with a certificate verifying said insurance. Said certificate shall state that the Owner shall be given 10 days advance written notice before any provisions -19- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 of the policies are changed or in the event said poli- cies shall be cancelled. This Certificate of Insur- ance shall be provided to the Owner prior to starting any construction work in connection with this Con- tract. 7. TERMINATION OF CONTRACT 7.01 Right of Owner to Terminate. If the Contractor should be gui ty of substantial violation of the Contract or any provision thereof, the Owner, upon certification by the Engineer as to the nature and extent of such violation, may without prejudice to any other resourc- es or remedy give the Contractor written notice of termination of the employment of the Contractor 10 days subsequent to such notice. Immediately following such date the Owner may take possession of the site of the work and all material, equipment, tools, and ap- pliances thereon and may finish the work in accordance with the provisions of Section 8 "Abandonment of Con- tract by Contractor ", of these General Conditions. 7.02 Right of Contractor to Terminate. If work should be stopped by order of any public authority or court through no act or fault of the Contractor for a period of three (3) months or if the Owner should substan- tially fail to perform the provisions of the Contract with regard to Owner's obligations to the Contractor, then the Contractor may, upon 10 days written notice to the Owner, terminate this Contract and recover from the Owner payment for all completed work. 7.03 Removal of Equipment. In the event that the Contract should be terminated for any reason whatsoever, the Owner may request the Contractor in writing to remove any or all of his equipment, tools, and supplies, and the Contractor shall comply with the request within 10 days after receipt of the notice. Should he fail to do so within 10 days after receipt of such notice, the Owner shall have the right to remove such equipment and supplies at the expense of the Contractor and to place such equipment, tools and supplies in storage at the risk and expense of the Contractor. 8. ABANDONMENT OF CONTRACT BY CONTRACTOR 8.01 Notification of Contractor. If the Contractor should abandon and fail to refuse to resume work within 10 -20- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 days after written notification from the Owner or the Engineer or if the Contractor fails to comply with the orders of the Engineer when such orders are consistent with this Contract or with the specifications hereto attached, then the Contractor shall be deemed as hav- ing abandoned the Contract. In such event the Surety on the bond shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the Contractor. 8.02 Retention of Contractor's Equipment and Materials by Owner. After receiving said notice of abandonment the Contractor shall not remove from the work any machin- ery, equipment, tools, materials, or supplies then on the job, but the same together with any materials and equipment under contract for the work may be held for use on the work by the Owner or the Surety on the per- formance bond or another contractor in completion of the work; and the Contractor shall not receive any rental or credit therefor except when used in connec- tion with extra work where credit shall be allowed as provided for under Section 2.12 entitled "Extra Work ", it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and will be reflected in the final settle- ment. 8.03 Methods of Completing the Work. If the Surety should fail to commence compliance with the notice for com- pletion hereinbefore provided within 10 days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: a. The Owner may thereupon employ such force of work- ers and use such machinery, equipment, tools, mat- erials, and supplies as said Owner may deem neces- sary to complete the work and charge the expense of such labor, machinery, equipment, tools, mater- ials, and supplies to said Contractor, and the ex- pense so charged shall be deducted and paid by the Owner out of such monies as may be due or that may thereafter at any time become due to the Contrac- tor under and by virtue of this Contract. In case such expense is less than the sum which would have been payable under this Contract if the same had been completed by the Contractor, then said Con- tractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this Contract if the same -21- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 had been completed by said Contractor, then the Contractor or his Surety shall pay the amount of such excess to the Owner. b. The Owner under sealed bids, after 14 days notice published two or more times in a newspaper having a general circulation in the county of location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this Contract. In case of any increase in cost to the Owner under the new contract as compared to what would have been the cost under this Contract such increase shall be charged to the Contractor, and the Surety shall be and remain bound therefor. However, should the cost to complete any such new contract prove to be less than what would have been the cost to complete under this Contract, the Contrac- tor or his Surety shall be credited therewith. 8.04 Final Acceptance. When the work has been completed the Contractor and his Surety shall be so notified and a Contract Completion Certificate as hereinafter pro- vided shall be issued. A complete itemized statement of the Contract accounts certified by the Engineer as being correct shall then be prepared and delivered to the Contractor and his Surety, whereupon the Contrac- tor, his Surety or the Owner, as the - may be, shall pay the balance due as reflected by said state- ment within 15 days after the date of such Contract Completion Certificate. 8.05 Disposition of Contractor's Equipment. In the event the statement of accounts shows that the cost to com- plete the work is less than that which would have been the cost to the Owner had the work been completed by the Contractor under the terms of this Contract or when the Contractor or his Surety pay the balance shown to be due by them to the Owner, then all machin- ery, equipment, tools, materials, or supplies left on the site of the work shall be turned over to the Con- tractor or his Surety. Should the cost to complete the work exceed the contract price, and the Contractor or his Surety fail to pay the amount due the Owner within the time designated hereinabove, and there re- mains any machinery, equipment, tools, materials, or supplies on the site of the work, notice thereof to- gether with an itemized list of such equipment and materials shall be mailed to the Contractor and his Surety at the respective addresses designated in this -22- Contract; provided, however, that actual written notice given in any manner will satisfy this condi- tion. After mailing or other giving of such notice such property shall be held by the Owner at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After 15 days from the date of said notice the Owner may sell such machinery, equipment, tools, materials, or supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety. Such sale may be made at either pub- lic or private sale, with or without notice, as the Owner may elect. The Owner shall release any machin- ery, equipment, tools, materials, or supplies which remain on the work and belong to persons other than the Contractor or his Surety to their proper owners. 9. MEASUREMENT AND PAYMENT 9.01 Character of Measurements. No extra or customary measurements of any kind will be allowed, but the actual length, area, solid contents, number, and weight only shall be considered unless otherwise spe- cifically provided. 9.02 Estimated vs. Actual Quantities. Any and all estimat- ed quantities stipulated in the proposal form under unit price items are approximate and are to be used only (a) as a basis for estimating the probable cost of the work and (b) for the purpose of comparing the proposals submitted for the work. It is understood and agreed that the actual amounts of work done and materials furnished under unit price items may differ from such estimated quantities and that the basis of payment for such work and materials shall be for the actual amount of such work done and the actual quan- tity of materials furnished. The Contractor agrees that he will make no claim for damages, anticipated profits, or otherwise on account of any difference between the amounts of work actually performed and materials actually furnished and the amounts estimated therefor in the proposal or other Contract Documents; provided, however, that if the actual quantity of any item should become as much as 25 percent more than or 25 percent less than the esti- mated or contemplated quantity for such items, then either party to this Contract shall be entitled upon demand to a revised consideration on the portion of -23- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 the work above or below 25 percent of the estimated quantity prior to initiating work or furnishing mater- ials for the overrun or underrun quantities. Such re- vised consideration shall be determined by agreement between the parties or otherwise by the terms of this Contract as provided under Section 2.12 entitled "Extra Work ". 9.03 Payment. In consideration of the furnishing of all the necessary labor, equipment, and material and the completion of all work by the Contractor, and on the completion of all work and the delivery of all mater- ial embraced in this Contract in full conformity with the specifications and stipulations contained herein, the Owner agrees to pay the Contractor the amounts set forth in the Proposal attached hereto which has been made a part of this Contract. The Contractor hereby agrees to receive such amounts in full payment for furnishing all material and all labor required for the aforesaid work, for all expense incurred by him, and for well and truly performing the same and the whole thereof in the manner and according to this Contract, the attached specifications, and requirements of the Engineer. 9.04 Monthly Estimates and Payments. On or about the fifth day of each month the Engineer will make an approxi- mate estimate of the value of work done in conformity with the plans and specifications during the previous calendar month. The Contractor shall furnish to the Engineer such detailed information as he may request to aid him as a guide in the preparation of monthly estimates. After each such estimate shall have been approved by the Owner, the Owner shall pay to the Con- tractor 90 percent of the amount of such estimated sum on or before the 15th day of said month. It is understood, however, that in case the whole work is near to completion and some unexpected or unusual delay occurs due to no fault or neglect on the part of the Contractor, the Owner may, upon written recommen- dation of the Engineer, pay a reasonable and equitable portion of the retained percentage to the Contractor. 9.05 Certificates of Completion. Within 10 days after the Contractor has given the Engineer notice that the work has been completed the Engineer shall inspect the work and satisfy himself by examination and test that the work has been finally and fully completed in accor- dance with the plans, specifications and Contract. If -24- 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 so, the Engineer shall issue a Contract Completion Certificate to the Owner and the Contractor. Such certificate when issued shall constitute final accep- tance of the work covered under this Contract. 9.06 Final Estimate and Payment. After the Contract Com- pletion Certificate has been issued the Engineer shall proceed to make final measurements and to prepare a final estimate of the work done and materials furnish- ed under this Contract and the value thereof. The Engineer shall certify the Final Estimate and submit it to the Owner within five (5) days from the date of the Contract Completion Certificate. The Owner shall pay the Contractor within 15 days from the date of the Contract Completion Certificate the entire sum shown due on the certified Final Estimate prepared by the Engineer after deducting all amounts to be kept and retained under any provision of this Contract. However, it is to be specifically under- stood that the final payment will not be paid by the Owner to the Contractor under any circumstances until the Notarized Affidavit required by Section 9.07 en- titled "Notarized Affidavit ", has been submitted to the Engineer. - All prior estimates and payments shall be subject to correction in the final estimate and payment; but in the absence of error or manifest mistake, it is agreed that all estimates, when approved by the Owner, shall be conclusive evidence of the work done and materials furnished. 9.07 Notarized Affidavit. Before final payment for the work by the Owner the Contractor shall submit to the Engineer a notarized affidavit in duplicate stating under oath that all subcontractors, vendors, and other persons or firms who have furnished or performed labor or furnished materials for the work have been fully paid or satisfactorily secured. Such affidavit shall bear or be accompanied by a statement, signed by the Surety Company who provided the performance bond for the work, to the effect that said Surety Company con- sents to final payment to the Contractor being made by the Owner. 9.08 Release of Liability. The acceptance by the Contrac- tor of the last payment shall operate as and shall be a release to the Owner and every officer and agent thereof from all claims and liability hereunder for anything done or furnished for or relating to the work or for any act or neglect of the Owner or of any per- son relating to or affecting the work. -25- TECHNICAL SPECIFICATIONS 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 SECTION 01 - GENERAL Page 01 -01 Scope of Work 1 01 -02 Construction Site 1 01 -03 Backwork 1 01 -04 Grading 1 01 -05 Surface Drainage 2 01 -06 Backfill 2 01 -07 Inspection of Work 2 01 -08 Notification 2 01 -09 Construction Staking 2 01 -10 Testing & Acceptance of Improvements . 3 01 -11 Work in Freezing Weather 3 01 -12 Protection of Trees, Plants & Shrubs 3 01 -13 Barricades 3 01 -14 Property Lines and Monuments 3 01 -15 Disposal of Surplus Material 3 01 -16 Contractor's Use of Premises 3 01 -17 Trade Names 4 01 -18 Materials and Workmanship 4 01 -19 Measurement and Payment 4 SECTION 02 - EARTHWORK INDEX TECHNICAL SPECIFICATIONS 02 -01 General 1 02 -02 Clearing and Grubbing 1 02 -03 Protection of Existing Structures & Utilities 2 02 -04 Maintaining Drainage 2 02 -05 Blasting 3 02 -06 Piling Excavated Material 3 02 -07 Shoring, Sheeting and Bracing 3 02 -08 Seasonal Limits 3 02 -09 Control of Dust 4 02 -10 Barricades, Guards, & Safety Provisions 4 02 -11 Excess Material 4 02 -12 Trench Excavation 4 02 -13 Trench Backfill 6 02 -14 Structural Excavation & Backfill . 8 02 -15 Earthfill Construction 10 02 -16 Measurement and Payment 13 i 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 SECTION 03 - CONCRETE Page 03 -01 General 1 03 -02 Scope 1 03 -03 Portland Cement 1 03 -04 Aggregates 2 03 -05 Water 3 03 -06 Admixtures 3 03 -07 Proportioning 4 03 -08 Mixing 5 03 -09 Concrete Consistency 5 03 -10 Transit Mixers 7 03 -11 Hand Mixing 8 03 -12 Transporting Batched Materials & Mixed Concrete 8 03 -13 Steel Reinforcement for Concrete 9 03 -14 Expansion Joint Filler and Joint Sealants 10 03 -15 Concrete Construction 13 03 -16 Finishing Types 22 03 -17 Openings for Installation of, and Preparation for, Other Work 25 03 -18 Defective Work 26 03 -19 Tests 26 03 -20 Cleaning 27 03 -21 Measurement and Payment 27 SECTION 04 - PIPING 04 -01 General 1 04 -02 Materials 3 04 -03 Plumbing 6 04 -04 Installation of Pressure Lines 8 04 -05 Installation of Gravity Lines 10 04 -06 Cleaning, Testing and Disinfection . 10 04 -07 Pipe Insulation 12 04 -08 Measurement and Payment 13 SECTION 05 - VALVES, GATES AND APPURTENANCES 05 -01 General 1 05 -02 Valves 2 05 -03 Measurement and Payment 6 ii 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 SECTION 06 - ELECTRICAL Page 06 -01 Scope 1 06 -02 Applicable Specifications & Standards . 1 06 -03 General Conditions 1 06 -04 Plans and Specifications 1 06 -05 Codes, Permits and Inspections 2 06 -06 Progress and Guarantee 2 06 -07 Cutting;

The Contractor shall, at his own expense, maintain the street free from dust, mud, excess earth or de- bris which constitutes a nuisance or danger to the public using the thoroughfare, or the occupants of adjacent properties. Care shall be taken to prevent spillage on streets over which hauling is done, and any such spillage or debris deposited on streets, due to the Contractor's operations, shall be immediately removed. 01 -03 BACKWORK The Contractor shall coordinate his operations in such a manner as to prevent the amount of clean -up and completion of back works from becoming exces- sive. Should such a condition be existent, the Engineer may order all or portions of the work to cease and refuse to allow any work to commence until the back work is done to the Engineer's satisfac- tion. 01 -04 GRADING The Contractor shall do such grading in the area adjacent to backfilled trenches and structures as may be necessary to leave the area in a neat and satisfactory condition approved by the Engineer. 01 -1/4 3/83 01 -05 SURFACE DRAINAGE All grading in the vicinity of trench excavation shall be controlled to prevent surface water from flowing into the trenches. Any water accumulated in the trenches shall be removed by pumping or by other approved methods. 01 -06 BACKFILL During excavation, material suitable for backfilling shall be piled in an orderly manner, a sufficient distance back from the edges of trenches, to avoid overloading and to prevent slides or cave -ins.. Materials unsuitable for backfilling shall be hauled from the job site and disposed of by the Contrac- tor. Where the Plans and /or Special Provisions provide for segregation of top soil from underlying material for purposes of backfill, the materials shall not be mixed. 01 -07 INSPECTION OF WORE The work covered under this Contract shall be in- spected by the Engineer or the Owner's authorized representative. The quality of material and the quality of installation of pipe and related equip- ment shall be to the satisfaction of the Inspector. It shall be the Contractor's responsibility for the construction methods and safety precautions in the undertaking of this Contract. 01 -08 NOTIFICATION The Engineer must be notified a minimum of 24 -hours in advance of beginning construction. 01 -09 CONSTRUCTION STAKING The Engineer will provide reference hubs and bench marks at the Booster Pump Station site. The Contractor shall provide his own construction staking. 01 -2/4 3/83 01 -10 TESTING AND ACCEPTANCE OF IMPROVEMENTS The Engineer or his representative will be present at the testing of water and sewer lines. The Con- tractor will test all lines and be confident that the lines will be able to pass test prior to calling the Engineer to observe test. No lines will be ac- cepted by the Owner without the Engineer observing the test and certifying to the lines passing the pressure tests as specified herein. 01 -11 WORK IN FREEZING WEATHER Portions of the work may continue as directed by the Engineer. 01 -12 PROTECTION OF TREES, PLANTS AND SHRUBS The Contractor shall take necessary precautions to preserve all existing trees, plants and shrubs but where it is justifiable and necessary, the Contrac- tor may remove trees and plants for construction right -of -way but only with prior approval of the Engineer. 01 -13 BARRICADES Barricades shall be installed, in locations deemed necessary by the Engineer, for the protection of life and property. Under no circumstances will any existing road be permitted to remain closed over a weekend. 01 -14 PROPERTY LINES AND MONUMENTS The Contractor shall be responsible for the protec- tion, reference and resetting of property corner monuments if disturbed. 01 -15 DISPOSAL OF SURPLUS MATERIAL The Contractor shall at his own expense make ar- rangement for the disposal of surplus material, such as rock, trees, brush and other unwanted backfill materials. 01 -16 CONTRACTOR'S USE OF PREMISES The Contractor shall, at his own expense, provide additional space as necessary for his operations and storage of materials. 01 -3/4 3/83 01 -17 TRADE NAMES Except as specified otherwise, wherever in the Specifications an article or class of material is designated by a trade name or by the name or catalog number of any maker, patentee, manufacturer, or dealer, such designations shall be taken as intend- ing to mean and specify the articles described or another equal thereto in quality, finish, and ser- viceability for the purpose intended, as may be determined and judged by the Engineer in his sole discretion. 01 -18 MATERIALS AND WORKMANSHIP No material which has been used by the Contractor for any temporary purpose whatever is to be incor- porated in the permanent structure without written consent of the Engineer. Where materials or equip- ment are specified by a trade or brand name, it is not the intention of the Owner to discriminate against an equal product of another manufacturer, but rather to set a definite standard of quality for performance, and to establish an equal basis for the evaluation of bids. Where the words "equivalent ", "proper ", or "equal to are used, they shall be understood to mean that the item referred to shall be proper, the equivalent of, or equal to some other item, in the opinion or judgment of the Engineer. Unless otherwise specified, all materials shall be the best of their respective kinds and shall be in all cases fully equal to approved samples. Notwith- standing that the words "or equal to" or other such expressions may be used in the specifications in connection with a material, manufactured article or process, the material, article or prices specifical- ly designated shall be used, unless a substitute shall be approved in writing by the Engineer, and the Engineer shall have right to require the use of such specifically designated material, article or process. 01 -19 MEASUREMENT AND PAYMENT No separate payment for work performed under this item. Include cost of same in contract price bid for items of which this work is a component. 01 -4/4 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 SECTION 02 - EARTHWORK 02 -01 GENERAL Earthwork shall consist of clearing, grubbing, loosening, blasting, rock excavation, removing, transporting, depositing, compacting, trenching, backfilling in final location all materials, wet or dry as required for construction; together with furnishing, placing and removing of all sheeting and bracing; and all pumping and draining of exca- vation. 02 -02 CLEARING AND GRUBBING 02 -02.1 General This work shall consist of removing all natural and artificial objectionable material from the right - of -way, construction areas and such other areas as may be specified. Clearing and grubbing shall be performed in advance of grading operations and in accordance with the requirements herein specified, subject to erosion control requirements. Demoli- tion of buildings and structures, other than foun- dations or slabs, shall be as specified on the plans. 02 -02.2 Preservation of Property Existing improvements, adjacent property, utility and other facilities, and trees and plants are not to be removed, and shall be protected from injury or damage resulting from the Contractor's opera- tions. 02 -02.3 Clearing and Grubbing Operations Unless otherwise specified, the entire area of the project to the widths specified below shall be cleared and grubbed. No payment will be made to the Contractor for clearing and grubbing outside these limits, unless such work is authorized by the Engineer. The area above the natural ground surface shall be cleared of all vegetable growth, such as trees, logs, upturned stumps, roots of downed trees, brush, grass, weeds, and all other objectionable material, within the limits of the roadways and yard area. 02 -1/13 3/83 Trees and plants that are not to be removed shall be fully protected from injury by the Contractor at his expense. 02 -03 PROTECTION OF EXISTING STRUCTURES AND UTILITIES Existing power and telephone lines, trees, fences, pipelines or other conduits, and structures in the vicinity of the work shall be supported and pro- tected from injury by the Contractor during the construction and until the completion of the work. The Contractor shall be liable for all damages to such structures, as herein provided, and shall save and keep the Owner harmless from any liability or expense for injuries, damages, or repairs to same. A thorough attempt has been made to show the type, size, location and number of all utilities, how- ever, no guarantee is made as to the location and number of utilities. The Contractor shall repair, in a manner satisfactory to the Engineer, all util- ities damaged in the progress of his work. The Contractor shall notify all owners of utilities prior to commencement of and sufficiently in ad- vance to have the utilities mark the location of their facilities. The Contractor shall be prepared at all times with labor, equipment, and materials to make repairs to damaged mains or utilities. 02 -04 MAINTAINING DRAINAGE The Contractor shall provide and maintain temporary drainage for all excavations, drains, ditches, trenches, and structures. The Contractor shall keep the excavations dry through the construction operations. Whenever necessary, in order to pro- vide proper drainage, the Contractor shall, at his own expense, install underdrains, furnish and ope- rate all necessary pumping equipment, drainage sumps, wellpoint systems and other drainage facil- ities. The Contractor shall dispose of the water from the work into a drainage channel without damage to ad- jacent property and in such a manner as not to be a menace to the public health. No water shall be drained into completed work or work under construc- tion without prior consent of the Engineer. 02 -2/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 The Contractor shall provide, without additional compensation, suitable temporary channels or other work for the water that may flow along or across the site of the work. 02 -05 BLASTING Blasting for excavation will be permitted only after securing the approval of the Engineer and only when proper precautions are taken for the pro- tection of persons and property. The hours of blasting will be fixed by the Engineer. Any damage caused by blasting shall be repaired by the Con- tractor at his expense. The Contractor shall carry proper and adequate blasting insurance. The Contractor's methods of procedure in blasting shall conform to federal, state, and local laws. 02 -06 PILING EXCAVATED MATERIAL All excavated material shall be piled in a manner that will not endanger the work and that will avoid obstructing roads and driveways. Hydrants under pressure, valve pit covers, valve boxes, curb stop boxes, fire and police call boxes, or other utility controls shall be left unobstructed and accessible until the work is completed. Gutters shall be kept clear or other satisfactory provisions made for street drainage. Natural watercourses shall not be obstructed. 02 -07 SHORING, SHEETING AND BRACING Where necessary, trenches and other excavations shall be properly sheeted and braced to furnish acceptable working conditions. The bracing shall comply in all respects to the rules, orders, and regulations prescribed by federal, state and local laws. When required by law, the Contractor shall submit to the Engineer detailed drawings of propos- ed bracing. 02 -08 SEASONAL LIMITS No fill material shall be placed, spread, or com- pacted during unfavorable weather conditions. When the work is interrupted by snow or rain, filling operations shall not be resumed until field tests 02 -3/13 3/83 by the Engineer indicate that the moisture content and density of the fill are as specified. 02 -09 CONTROL OF DUST The Contractor shall, at all times, keep the con- struction area watered or swept of all loose mater- ial produced by his operations in order that traf- fic and construction do not raise an objectionable amount of dust. When conditions warrant, the Con- tractor shall apply a suitable dust palliative to control dust. 02 -10 BARRICADES, GUARDS, AND SAFETY PROVISIONS To protect persons from injury and to avoid proper- ty damage, adequate barricades, construction signs, torches, red lanterns, and guards, as required, will be placed and maintained during the construc- tion. All material piles, equipment, and pipe which may serve as obstructions to traffic shall be enclosed by fences or barricades and shall be pro- tected by proper lights when the visibility is poor. The rules and regulations of the local authorities respecting safety provisions shall be observed. 02 -11 EXCESS MATERIAL Excess excavation material shall be promptly remov- ed and disposed of on the site by the Contractor as directed by the Engineer. The Contractor shall not dump material on any private property without the written permission of the Owner thereof. 02 -12 TRENCH EXCAVATION 02 -12.1 Trenching Trenches shall be of such extra width, when requir- ed, as will permit the convenient placing of timber supports, sheeting and bracing, and handling of specials. All excavations for pipes shall be of a depth to permit at least a thirty inch (30 ") cover- ing over the pipe unless otherwise shown. All trenches shall have vertical sides from the bottom to a point at least twelve inches (12 ") above the top of the pipe. Above this point in unstable ground, with the written consent of the Engineer, the trench banks may be sloped as directed. 02 -4/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Bell holes shall be provided at each joint to per- mit the jointing to be made properly, unless other- wise approved by the Engineer. The bottom of trench must be free from loose mater- ial before placing the subgrade material. Whenever the maximum allowable trench width is exceeded for any reason, the Contractor shall, at his expense, embed or cradle the pipe in concrete in a manner satisfactory to the Engineer. 02 -12.2 Pipe Clearance in Rock Ledge rocks, boulders, and large stones shall be removed to provide a clearance of not less than six inches (6 ") below and on each side of all pipe, valves, and fittings. 02 -12.3 Excavation in Poor Soil and Refilling to Grade Where the bottom of the trench at subgrade is found to be unstable or to include ashes, cinders, any type of refuse, vegetable or other organic mater- ial, or large pieces of fragments or inorganic material which, in the judgment of the Engineer are unsuitable, the Contractor shall excavate and re- move such unsuitable material to the width and depth ordered by the Engineer. Before the pipe is laid, the subgrade shall be made by backfilling as provided herein. Payment for over excavation and refilling to grade will be made in accordance with the General Condi- tions. Unsuitable excavation shall be removed from the project. 02 -12.4 Braced and Sheeted Trenches Open -cut trenches shall be sheeted and braced as required by applicable regulations, and as may be necessary to protect life, limb, property, or the work. When close sheeting is required by trench conditions, it shall be so driven as to prevent ad- jacent soil from entering the trench below or through such sheeting. Where sheeting and bracing are used, the trench width shall be increased ac- cordingly. The Engineer reserves the right to order the sheet- ing driven to the full depth of the trench or to 02 -5/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 such additional depths which are required for the protection of the work. Where the soil in the lower limits of a trench has the necessary stabil- ity, the Engineer, at his discretion, may permit the Contractor to stop the driving of sheeting at some designated elevation above the trench bottom. Any sheeting driven below the invert grade shall be left in place. The granting of such permission by the Engineer, however, shall not relieve the Con- tractor in any degree from his full responsibility under the Contract. Sheeting and bracing which are left in place must be removed for a distance of three feet (3') below the established finished grade or the existing sur- face, whichever is lower. Trench bracing, except that which must be left in place, may be removed when the backfilling has reached the respective levels of such bracing. Sheeting, except that which must be left in place, must be removed after the backfilling has been completed or has been brought up to such an elevation as to permit its safe removal. Sheeting and bracing may be removed before backfilling but only in such manner as will insure the adequate protection of the adjacent structures. 02 -13 TRENCH BACKFILL 02 -13.1 General Pipeline trenches shall be backfilled with desig- nated materials to the level of the original ground surface, to the underside of the ground base course, to the finished grade, or as shown on the drawings. Before backfilling, the trench shall be cleared of all timber and debris. Backfill shall be compacted to 85% relative density except as otherwise provided herein. It is highly important that a dense, well- compacted backfill be placed around the pipelines. The Con- tractor will be required to produce such a backfill under all circumstances. The materials used for the backfill, the amount thereof, and the manner of deposition shall be subject to the approval of the Engineer, but the Contractor will be held respons- ible for any displacement or instability of the pipeline or any damage to the coating caused by im- proper installation of backfill materials. No 02 -6/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 material shall be used for trench backfill, which, for any reason cannot be compacted to the degree specified. For these specifications, backfill shall be divided into two (2) categories: Bedding and Upper Zone Backfill. Bedding shall be defined as that mater- ial supporting and extending to one foot (1') above the top of the pipe. Where concrete is specified to cover the pipe, the top of the concrete shall be considered as the top of the bedding. Upper zone backfill shall be defined as that material placed in the trench from the top of the bedding to the upper limit of backfill required. 02 -13.2 Bedding In soft, spongy, unstable, or other similar mater- ial is encountered upon which the bedding material or pipe is to be placed, this unsuitable material shall be removed to a depth ordered by the Engineer and replaced with bedding material suitably densi- fied. Additional bedding so ordered, over the above amount required by the plans or specifica- tions, will be paid for as provided in the General Conditions. If the necessity for such additional bedding materials has been caused by an act or failure to act on the part of the Contractor, or is required for the control of ground water, the Con- tractor shall bear the expense of the additional excavation and bedding. Bedding material shall first be placed so that the pipe is supported for the full length of the barrel with full bearing on the bottom segment of the pipe equal to a minimum of 0.4 of the outside diameter of the barrel. Then the remainder of the bedding shall be placed. Alternate methods of pipe laying which are recommended by the pipe manufacturer may be used if approved by the Engineer. Refer to "Pipe Bedding" detail at end of these specifications. The pipe bedding over the top of the pipe shall be compacted to 90 percent relative compaction unless otherwise shown on the drawings. 02 -7/13 3/83 1 1 1 1 1 1 I 1 1 1 1 1 1 1 1 1 1 1 1 02 -13.3 Upper Level Backfill Backfill material for the upper level backfill zone of the pipe trench shall be native material com- pacted to 85 percent relative compaction. In roadway or parking areas, all backfill shall be compacted to 90 percent relative compaction. Jetting (water consolidation of backfill) shall be used only when approved by the Engineer. The jet pipe shall be not less than one and one -half (1 -1/2) inches in diameter and shall extend to within fifteen inches (15 ") of the top of the pipe during jetting of backfill over pipe. The source of water for jetting shall be a water tank with a pressure of sixty pounds (60) per square inch. All "bridges" shall be completely broken down during the jetting process. Jet points along the line of the ditch shall be staggered from side to side at intervals not to exceed six feet (6') center to center or as necessary so that the backfill takes full possible subsidence while water is being in- troduced into it through the jet pipe. If the com- paction requirements specified above are not met within 60 calendar days after jetting the backfill, the trench shall be re- excavated. Backfill mater- ial shall then be compacted by tamping and /or roll- ing until the compaction requirements are satis- fied. Backfill must have no rocks larger than 5" in its greatest dimension. 02 -14 STRUCTURAL EXCAVATION AND BACKFILL 02 -14.1 Excavation The Contractor may employ any method of excavation that he desires which, in his experience, he con- siders to be the best, providing it meets with the approval of the Engineer. The ground shall not be dug by machinery nearer than three inches (3 ") of any finished subgrade without the express consent and approval of the Engineer. The last three inch- es (3 ") shall be removed by such methods acceptable to the Engineer, and shall not disturb or weaken any subgrade for foundation purposes. 02 -8/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Excavations for footing, floor slabs, and other structures shall be carried to the neat outside lines of such structures, as shown on the drawings, plus one inch (1 ") in all horizontal directions, and the concrete to be poured therein shall be placed on or against the original undisturbed material whenever such a procedure is reasonably possible and expedient. If this is not possible, the earth on which the concrete is to be poured shall be compacted to a uniform density of not less than ninety percent (90%) of the maximum density. Excavations for walls, where forms are used, shall extend a sufficient distance to allow for placing and removal of forms, installations of services, and inspection of work. Structure excavation carried beyond or below the lines and grades indicated on the drawings shall be refilled with approved materials and compacted as directed by the Engineer at the expense of the Con- tractor, except that under footings, concrete shall be used. 02 -14.2 Backfilling All lumber, rubbish and braces shall be carefully removed from excavations. Unless otherwise speci- fied, all excavations shall then be backfilled with imported material up to the original surface of the ground, or to such grades as shall be directed. The backfilling shall be done as completely as pos- sible in such manner as to prevent after- settle- ment. No backfill shall be placed against concrete walls until the walls have been inspected and approved by the Engineer. Shoring and sheeting shall be care- fully and completely removed as the backfilling progresses, unless otherwise authorized by the Engineer. Where sheeting is left in place, all cavities behind such sheeting shall be solidly filled. Aggregate under floor slabs, as called for on the drawings, shall meet the following specifications and be compacted to 90 percent of the maximum den- sity. 02 -9/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Sieve Size Percentage Passing Sieve 1" 100 3/4" 90 -100 No. 4 0- 10 Backfill material shall be placed in horizontal, uniform layers not exceeding eight inches (8 ") in thickness before compaction, and shall be brought up uniformly on all sides of the structure or facility. Each layer of backfill shall be compact- ed to a relative compaction of not less than 90 percent. Consolidation of structure backfill by ponding and jetting will be permitted when as determined by the Engineer, the backfill material is of such charac- ter that it will be self- draining when compacted and that foundation materials will not soften or be otherwise damaged by the applied water, and no damage to the structure from hydrostatic pressure will result. When ponding and jetting is permit- ted, material for use as structure backfill shall be placed and compacted in layers not exceeding four feet (4') in thickness. The work shall be performed without damage to the structure or soft- ening of the embankment and in such a manner that excess water will not be impounded. Ponding and jetting methods shall be supplemented by the use of vibratory or other consolidation equipment when necessary to obtain the required consolidation. Backfill material shall be native material provided that no material larger than three inches (3 ") in greatest dimension shall be used. 02 -15 EARTBFILL CONSTRUCTION 02 -15.1 General Earth fill construction shall consist of construct- ing embankments, including the preparation of the areas upon which they are to be placed; buttress fills, dikes; the placing and compacting of approv- ed material within areas where unsuitable material in holes, pits and other depressions. Areas over which fills are to be placed shall be cleared and scarified to provide a bond between the existing ground and the material to be deposited thereon. When fills are to be placed over existing 02 -10/13 3/83 surface improvements which are to remain in place, such clearing and scarifying will not be required. When fill is to be made and compacted on hillsides or where new fill is to be compacted against exist- ing fill or where embankment is built one -half width at a time, the slopes or original hillsides and old or new fills shall be benched a minimum of four feet (4') horizontally as the fill is placed. A new bench shall be started where the vertical cut for the next lower bench intersects the existing ground. Material thus cut out shall be recompacted along with the new embankment material at the Contrac- tor's expense. Clods or hard lumps of earth of six inches (6 ") in greatest dimension shall be broken up before com- pacting the material in embankment, with the fol- lowing exception: When the fill material contains large rocks, boul- ders, or hard lumps (such as hardpan or cemented gravel which cannot be broken readily) over twelve inches (12 ") in greatest dimension, such materials may be incorporated in the fill only when authoriz- ed by the Engineer with respect to the acceptabil- ity of the material, the location and depth of its placement in the fill, and the method to be used. Embankments shall not be constructed when material is frozen or a blanket of snow prevents proper com- paction. 02 -15.2 Compacting Fill shall be constructed in compacted layers of uniform thickness and each layer shall be compacted in accordance with the requirements herein speci- fied with the following exception: Where fills are to be constructed across low, swam- py ground which will not support the weight of hauling equipment, the lower part of the embankment may be constructed by dumping successive loads in a uniformly distributed layer of a thickness not greater than that necessary to support the equip- ment while placing subsequent layers. The remain- der of the embankment shall be constructed in lay- ers and compacted as specified. 02 -11/13 3/83 The construction of dikes, the placing and compact- ing of approved material where unsuitable material has been removed, and the filling of holes, pits and other depressions, shall conform to all of the requirements specified herein for compacting fills. Trenches, holes, depressions and pits outside of areas where fills are to be constructed shall be graded to provide a presentable and well- drained area. Embankments shall be constructed so that each layer shall have a cross fall of at least two percent (2%) but no more than five percent (5%). The loose thickness of each lift of fill material shall not exceed that which will provide the speci- fied relative compaction through the full depth of the lift by the specific compaction equipment being utilized. Each lift shall be compacted in accor- dance with the following requirements to a relative compaction of not less than 85%. The interstices around the rock in each layer shall be filled with earth or other fine material and compacted. Broken portland cement concrete and bituminous type pavement obtained from the project excavations will be permitted in the fill with the following limitations: 1. The maximum dimension of any piece used shall be six inches. 2. Pieces larger than four inches (4 ") shall not be placed within twelve inches (12 ") of any structure. 3. Pieces larger than three inches (3 ") shall not be placed within twelve inches (12 ") of the finished surface. 4. "Nesting" of pieces will not be permitted. At locations where it would be impractical to use mobil power compacting equipment, fill layers shall be compacted to the specified requirements by any approved method that will obtain the specified re- lative compaction. At the time of compaction, the moisture content of fill material shall be such that the specified relative compaction will be obtained and the fill will be firm, hard and unyielding. Fill material which contains excessive moisture shall not be 02 -12/13 3/83 compacted until the material is dry enough to obtain the required relative compaction. Full compensation for any additional work involved in drying fill material to the required moisture content shall be considered as included in the contract price paid and no additional compensation will be allowed therefor. 02 -16 MEASUREMENT OF PAYMENT No separate payment for work performed under this Item. Include cost of same in Contract prices bid for item of which this work is a component part. 02 -13/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 SECTION 03 - CONCRETE 03 -01 GENERAL 03 -02 SCOPE Concrete consisting of portland cement, concrete ag- gregate, sand and water will be designated by a sym- bol consisting of a number, a letter and a number.

The Contractor shall furnish a certificate of compliance signed by the manufacturer identifying the cement and stating that the cement delivered conforms to ASTM C -150. 03 -1/27 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 03 -05 WATER Whenever suitable facilities, approved by the Engi- neer, are available for handling and weighing bulk cement, such facilities shall be used. Otherwise, the cement shall be delivered in original unopened sacks that have been filled by the manufacturer. They shall be plainly marked with the manufacturer's name or brand and cement type. Each sack shall con- tain 94 pounds of cement. Cement shall be stored in such a manner as to permit ready access for the purpose of inspection and sam- pling, and suitably protected against contamination or moisture. Should any cement show evidence of contamination, or be otherwise unsuitable, it shall not be used. All portland cement used in concrete for any indivi- dual structure shall be of the same brand and type unless otherwise approved by the Engineer. 03 -04 AGGREGATES Aggregates shall be sand and concrete aggregates conforming to the requirements prescribed in ASTM C -33 coarse aggregate gradation size number 467, and shall be approved by the Engineer prior to use. They shall meet the grading requirements of this subsection. Methods of handling materials resulting in segrega- tion, degradation or the combining of materials which result in any stockpile failing to meet speci- fications, shall not be permitted. Aggregates which are found to have a silica - released to alkali- reduced ratio greater than one, when test- ed in accordance with ASTM C289, may be used only when approved by the Engineer and provided low - alkali cement is used. Water used for concrete shall be clear and free from oil, vegetable matter and other deleterious substan- ces. Water shall not contain an amount of impurities that will cause a change in the time of setting of portland cement of more than 25 percent nor a reduc- tion in the compressive strength of mortar at four- teen days of more than 5 percent compared to results obtained with distilled water. 03 -2/27 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 In conventionally reinforced concrete work, water shall not contain more than 1,000 ppm of chlorides calculated as Cl, nor more than 1,000 ppm of sul- fates calculated as SO4. In non - reinforced concrete work, water shall not contain more than 2,000 ppm of chlorides calculated as Cl, no more than 1,500 ppm of sulfates calculated as SO4.. 03 -06 ADMIXTURES Air entrainment shall be required on exposed plant walls or as directed by the Engineer. The air con- tent shall not be less than 3% nor more than 6%. Admixture shall conform to ASTM C -260. Test shall be conducted in accordance with C -231, 233 or 173. Water reducer -set retarder admixture shall be used when average daily mean temperature is 75 ° F. or more per ASTM C -494. No other admixtures of any type shall be used unless authorized by the Engineer. When an admixture is permitted or specified, it shall be measured accu- rately into each batch or load in liquid form by a mechanical dispensing device and method approved by the Engineer. 03 -07 PROPORTIONING Aggregates and cement shall be proportioned by weight. Proportioning shall consist of combining the aggre- gates, each stored in a separate bin in the various gradations prescribed, with cement and water. Weigh hoppers shall be charged from bins located directly over them or from conveyor belts. When conveyor belts are used, there shall be a separate belt for each size aggregate. There shall be an approved moisture meter installed to indicate the moisture in the sand. Bulk cement shall be weighed in an individual hopper and shall be kept separate from the aggregates until the batch ingredients are discharged into the mixer drum. The cement hopper shall be attached to a separate scale for individual weighing. 03 -3/27 3/83 1 1 1 1 1 1 1 1 1 1 1� 1 1 1 1 1 1 1 1 The amount of water to be added to the mixture shall be measured and discharged rapidly into the mixing drum through a valve with a positive cut -off. When water is measured by weight it shall be weighed on a separate scale. All weighing or metering devices, except moisture meters, used for proportioning materials shall be accurate to within one percent. They shall be seal- ed and certified by the recognized, legal Sealer of Weights and Measures. These certifications shall be dated within the past 12 months and shall be renewed whenever required by the Engineer. The moisture meter shall be accurate to within 1/2 of one percent moisture. Whenever portable bunkers are set up at a new location, the scale assemblies shall be inspect- ed and certified regardless of the date the scales were last tested. Scales utilized in proportioning shall be either springless dial or multiple beam type. Scale gradu- ations shall be no greater than the following: Aggregate Scales Cement Scales Water Scales 25 lbs. 5 lbs. 5 lbs. All scales shall be of such size and so arranged that they may be read easily from the operator's platform. if a multiple beam type scale is used, the scale shall be provided with an indicator oper- ated by the main beam which will give positive visi- ble evidence of over or under weight. The indicator shall be so designed that it will operate during the addition of the last 400 pounds of any weighing. The over travel of the indicator hand shall be at least one -third of the loading travel. Indicators shall be enclosed against moisture and dust. Weighing equipment shall be insulated against vibra- tion and movement of other operating equipment in the plant.

Mixing shall be commenced as soon as possi- ble after the cement is placed in contact with the aggregates, but in no event shall the intervening period exceed 30 minutes. All concrete mixers shall be of such design and con- struction and so operated as to provide a thoroughly and properly mixed concrete in which the ingredients are uniformly distributed. Mixers shall be main- tained in proper and serviceable working condition and any part or portion thereof that is out of or- der, or becomes worn to such extent as to detrimen- tally affect the quality of mixing, shall be prompt- ly repaired or replaced. 03 -09 CONCRETE CONSISTENCY The amount of water added at the mixer shall be re- gulated to take into account the free water in the aggregates. Free water is defined as the total water minus the water absorbed by the aggregate in a saturated surface -dry condition. The amount of water used in the mixture shall not exceed the minimum amount necessary to permit prac- tical placement and consolidation of the concrete, and unless otherwise authorized by the Engineer, shall be that required to produce concrete with a slump within the range shown as nominal in the fol- lowing table: Type of Work Nominal Slump Maximum Slump (inches) (inches) Concrete Pavement 0 -2 3 Non - reinforced Concrete 0 -3 4 Reinforced Concrete Structures Heavy Sections 0 -3 5 Thin Sections & Columns 0 -4 6 Concrete Placed under Water 6 -8 9 03 -5/27 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 The concrete used in the work shall not have a slump greater than that shown as maximum above, nor a free water content greater than 312 pounds per cubic yard of concrete. When adverse or difficult conditions affect the placement of concrete, the Engineer may authorize a greater slump to be used, provided both the water and cement are increased. Water shall be added at a ratio not to exceed 30 pounds per sack of added cement per cubic yard of concrete, and such addi- tional water and cement shall be at the Contractor's expense. The consistency of concrete shall be determined in accordance with ASTM C -143. If slump tests of individual samples taken at appro- ximately the 1/4 and 3/4 points of the discharge differ by more than two inches (2 "), the mixer will not be acceptable for further use until the condi- tion is corrected. 03 -10 TRANSIT MIXERS The type, capacity, and manner of operation of the mixing and transporting equipment for ready -mix con- crete shall conform to the current ASTM C -94 stan- dard; "Standards for Operation of Truck Mixers and Agitators of the National Ready -Mixed Concrete Asso- ciation" and the "Truck Mixer and Agitators Stan- dards of the Truck Mixer Manufacturers Bureau ".

Each mixer shall have an identification number painted on the truck in such a location that it can be easily read from the batching platform. The total volume of materials introduced into the mixer shall not exceed the manufacturer's guaranteed mixing capacity. If the concrete so mixed does not 03 -6/27 3/83 1 1 1 1 1 t 1 1 1 1 1 1 1 1 1 1 1 1 1 meet the uniformity requirements of this subsection, the amount of materials charged into the mixer shall be reduced. The drum of the mixer shall be completely emptied of any previously mixed load. The proper proportions of aggregate, cement, and water for each load of concrete shall be placed in the mixer and shall be mixed therein for not less than 70 nor more than 100 revolutions of the drum or blades at the speed de- signated by the manufacturer of the equipment as mixing speed. Additional revolutions of the drum shall be at the speed designated by the manufacturer of the equipment as agitating speed. The revolving of the drum shall be continuous until the concrete is completely emptied from the drum. When concrete is being placed for concrete struc- tures, all wash water shall be emptied from the mix- er before any portion of the succeeding load is placed therein. For all other work, the mixer shall be empty or may carry 10 gallons of water in the drum. Adequate control of ready -mixed concrete will normally require that additional water be added and mixed into the batch at the point of discharge. Water so added shall be mixed into the load for a minimum mixing time of three (3) minutes. Water shall not be added to the load during transit. The total elapsed time between the addition of water at the batch plant and discharging the completed mix shall not exceed 90 minutes. Under conditions con- tributing to quick setting, the total elapse time permitted may be reduced by the Engineer. The Engineer shall be provided with a legible certi- fied weighmaster's certificate which shall contain the following information: Name of vendor Name of contractor Number of cubic yards in the load Actual weights of cement and of each size of aggregate Amount of water added at the plant Amount of water in the aggregate Brand and type of cement Brand and amount of admixture Time and date of batching 03 -7/27 3/83 1 r 1 1 1 1 1 1 1 1 1 1 1 Y 1 1 1 1 1 Space shall be provided on the certificate so that amount of water added on the job may be indicated. 03 -11 HAND MIXING Hand mixed concrete shall be mixed on a water -tight platform or in a mortar box in batches not to exceed 1/3 cubic yard each.

Nothing in the Drawings or Specifications is to be construed to permit work not conforming to these codes. When the Specifications call for materials or con- struction of a better quality or larger sizes than required by the above mentioned rules and regula- tions, the provisions of these Specifications shall 04 -6/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 take precedence over the requirements of the said rules and regulations. The Contractor shall furnish, without any extra charge, any additional material and labor when re- quired by the compliance with these rules and regu- lations, though the work be not mentioned in these particular Specifications or shown on the Draw- ings. Spaces are provided in the design for the construc- tion of the building to install the plumbing work and the Contractor shall keep all pipe within the furring lines established on the Drawings, unless pipes are shown exposed. All pipes shall be run in the approximate locations shown and shall be of sizes given on the Drawings. Unless otherwise shown, pipelines shall be run parallel to, or at right angles to, the structure. Piping must be offset wherever necessary to obtain head room. In all cases, pipelines shall be in- stalled to conform to the actual conditions found in the building such as offsetting to clear struc- tural members, etc. Holes for pipes through walls, domes, or ceiling shall be lined with 24 -gauge galvanized steel sleeves with one -half inch (1/2 ") flanges each end. Where all posed pipes pass through walls, ceilings, or floors, they shall be fitted (in lavatory and chlorine rooms) with chrome - plated plates.

Pipes through the roof shall be flashed and made watertight using SEMCO 6 pound seamless lead flash- ing with six inch (6 ") skirt- and -caulk type counter flashing sleeve. Wherever changes in sizes of piping occur, the changes shall be made with reducing fittings, as the use of bushings will not, in general, be per- mitted. Eccentric reducing fittings shall be used wherever necessary to provide free drainage of lines. All "horizontal" drainpipes within the building shall have a minimum of one - quarter -inch (1/4 ") pitch per foot, unless other marked or required to obtain the indicated inverts. 04 -7/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Cleanouts shall be installed where required or where indicated on Drawings. No cleanouts or valves shall be installed in inaccessible places. Where valves, traps, or cleanouts are installed in furred ceilings or walls, the Contractor shall fur- nish and install access plates and frames in the furring. The Contractor shall thoroughly clean all plumbing fixtures and trim free from rust, dirt, etc., be- fore any covering or painting is done or the system put in readiness for final inspection. The Contractor shall protect all vitreous - finished surfaces of fixtures with heavy paper plaster here- on, or by other means, throughout the period of construction. The piping system shall be flushed out until it is thoroughly clean in the judgement of the Engineer. All openings into pipes shall be effectively capped to keep foreign matter out while under construc- tion. After the completion of all work, all resulting debris shall be removed to leave the entire work in a complete and undamaged condition and the system adjusted to proper operation. 04 -03.3 Materials Fixtures: Fixtures are specified on the Plans. Floor Drains and Traps: Floor drains shall be cast iron as manufactured by number as shown on the Drawings. Traps shall be cast iron and shall be installed as near as possible to the unit which they service. Dielectric Fittings: Shall be provided wherever dissimilar metals are connected. 04 -04 INSTALLATION OF PRESSURE LINES 04 -04.1 General All pipe and fittings shall be carefully examined for defects and no piece shall be installed which is shown to be defective. Special care shall be 04 -8/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 taken to avoid leaving bits of wood, dirt, and foreign particles in the pipe. Every precaution shall be taken to prevent foreign material from entering the pipe while it is being placed in the line. If the pipe laying crew cannot place the pipe in the trench without getting earth into it, the Engineer may require that, before low- ering the pipe into the trench, a heavy, tightly woven canvas bag of suitable size shall be placed over each end and left there until the connection is to be made to the adjacent pipe. During laying operations, no debris, tools, clothing, or other materials shall be placed in the pipe. At times when pipelaying is not in progress, the open ends of pipe shall be closed by a watertight plug or other means approved by the Engineer. Pipe shall be laid with the bell ends or coupling ends facing in the direction of the laying unless directed otherwise by the Engineer or specifically indicated on the Drawings. All pipe shall be carefully placed and supported at the proper line and grade, and shall be sloped to permit drainage. Minor adjustment may be necessary to avoid architectural and structural features. Major relocations shall be approved by the Engi- neer. Minimum earth cover shall be 30 inches, un- less otherwise shown on the Drawings. Sufficient screw unions, flanges joints, or flex- ible couplings shall be used to allow the conven- ient removal of any run of pipe without removing adjacent runs or equipment. Where practicable, make -up joints have been indicated on the Drawings; however, omission of these joints from the Drawings does not excuse the Contractor from their installa- tion. Whenever a pipe larger than 3 inches in dia- meter is cast or grouted in place and passes from concrete to earth, a flexible coupling must be used on the earth side. Bare metal pipe passing from concrete to earth shall be wrapped with Scotch Wrap 50 for 3 inches each side of the concrete face on the earth side. Air piping from the air supply (compressor and receiver) to electric solenoid air control valve shall be galvanized iron pipe per Section 04 -02.3. 04 -9/13 3/83 1 1 1 1 1 1 r 1 1 1 1 1 1 1 1 1 1 1 1 Air piping from the electric solenoid air control valve to the pneumatic valve shall be copper pipe per Section 04 -02.7. Size of copper pipe per valve manufacturer's recommendations. 04 -05 INSTALLATION OF GRAVITY LINES Wherever possible, the Contractor shall avoid the distribution of pipe to the trench site too far in advance of the laying operations. The Contractor shall exercise care in the unloading of the pipe so as to avoid damage caused by the unloading opera- tions. Immediately preceding the laying of a length of sewer pipe, it shall be visually checked for dam- age, defects, and to ensure that the inside of the pipe is clean and free from debris. Both bell and spigot shall be clean before the joint is made, and care shall be taken that nothing but the joint- making material enters the joint. If water is encountered in the trench, it shall be kept below the bottom of the bell of the pipe. Should the water, through neglect or otherwise, rise in the trench before the jointing operation is completed, the anular space in all pipe so affected shall be freed of all water and foreign matter and thoroughly cleaned before completing the jointing operation. When pipe laying is not in progress, the forward end of the pipe shall be kept effectively closed with an approved temporary barricade. 04 -06 CLEANING, TESTING AND DISINFECTION 04 -06.1 General Pressure and gravity lines shall be cleaned of all foreign matter and tested in the presence and to the satisfaction of the Engineer. Leakage shall be corrected or, in the case of the sewer lines, shall be brought within the allowable limit at the Con- tractor's expense. The Contractor shall furnish the necessary pumps, labor, equipment, and materials, and shall assist the Engineer in making tests of the completed sys- tem before the system is placed in operation or connected to other lines. 04 -10/13 3/83 1 1 1 1 1 1 v 1 1 1 1 1 1 1 1 1 1 1 04 -06.2 Cleaning The gravity and pressure lines shall be flushed clean prior to testing or disinfection. 04 -06.3 Disinfection Potable water systems shall be disinfected in ac- cordance with AWWA C -601 "Procedure for Disinfect- ing Water Mains ". 04 -06.4 Testing 04- 06.4.1 Pressure Lines (Except Perforated Pipe) Each section of the pipe to be tested shall be slowly filled with water, and all air shall be expelled from the pipe. The release of the air can be accomplished by opening valves and service line cocks at the high points of the system and at all dead ends. The valves controlling the admission of water into the section of pipe to be tested should be opened wide before shutting high point valves and cocks. After the system has been filled with water and air expelled, all the valves controlling the section to be tested shall be closed, and the line be allowed to set for a period of not less than 24 hours. The system shall then be tested for a period of one (1) hour at a hydrostatic pressure of 150 psi or 1.5 times the maximum operating pres- sure. There shall be no leakage for an all- welded pipe- line or one joined with mechanical couplings. If defects are found or the line does not meet the allowable leakage rate, the Contractor shall locate the leaks, make the necessary repairs at his own expense, backfill, and repeat the pressure and leakage tests in the presence of the Engineer as specified above. No pipeline section shall be ac- cepted until the leakage is within the specified allowance. 04- 06.4.2 Air and Gas Piping Air and gas piping shall be tested for a period of four (4) hours at 100 psi or 1.5 times the operat- ing pressure, whichever is greater. There shall be no drop in pressure allowed. 04 -11/13 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 04- 06.4.3 Chlorine Solution Piping Chlorine solution piping shall be tested with air for a period of four (4) hours at a pressure of 100 psi.

Color shall be Dawn Blue #328. 07 -05 APPLICATION OF PAINT On metal surfaces, the painter shall apply each coat of paint at the rate specified by the manufac- turer to achieve the minimum dry mil thickness re- quired. If material has thickened or must be di- luted for application by spray gun, the coating 07 -4/6 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 shall be built up on the same film thickness achieved with undiluted material. In effect this means one (1) gallon of paint as originally fur- nished by the manufacturer must not cover a greater square foot area when applied by spray gun than when applied unthinned by brush. Deficiencies in film thickness shall be corrected by the applica tion of an additional coat of paint. On concrete, application rates will vary according to surface texture; however, in no case shall the manufactur- er's stated coverage rate be exceeded. On porous surfaces, it shall be the painter's responsibility to achieve a protective and decorative finish either by decreasing the coverage rate or by apply- ing additional coats of paint. Apply paint only when temperature and atmospheric conditions are favorable to drying, and are such to preclude condensation on surfaces to receive paint. Do not apply paint when either surface or ambient temperatures are less than 50 degrees Fahrenheit, or when temperature drop of 20 degrees, or below 50 degrees Fahrenheit is forecast. Do not apply paint to surfaces upon which there is frost or moisture, nor during misty or rainy weather unless specific approval is given. Do not apply finish field painting to machinery, equipment, or piping until operational testing has been completed. The Contractor shall submit to the Engineer, imme- diately upon completion of the job, certification from the manufacturer indicating that the quantity of each coating purchased was sufficient to proper- ly coat all surfaces. Such certification shall make reference to square footage figures provided to the manufacturer by the Contractor. Drying time shall be construed to mean "under nor- mal conditions ". Where conditions are other than normal because of the weather or because painting must be done on confined spaces, longer drying times will be necessary. Additional coats of paint shall not be applied, nor shall units be returned to service until paints are thoroughly dry. After installation of machinery and electrical equipment, check base coats carefully and retouch all damaged surface areas. Do not paint name- plates, serial number bases, chrome or bronze trim, or any rotating parts. Clean off any excess paint 07 -5/6 3/83 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 that impairs convenient removal of covers on gaug- es, instrumentation, or other equipment fitted with doors or covers. Thinners: Where thinning is necessary, only the products of the manufacturer furnishing the paint, and for the particular purpose, shall be allowed, and all such thinning shall be done strictly in accordance with the manufacturer's instructions, as well as with the full knowledge and approval of the Engineer. Colors: Unless specified on the Plans or elsewhere in these Specifications, color of the painted sur- faces shall be selected by the Engineer. Upon completion of the protective coating and painting, the Contractor shall remove all surplus materials and rubbish and remove all spattered material from surfaces where its presence is objec- tionable. All coated or painted surfaces shall be free from abrasion or other blemish when the pro- ject is ready for final acceptance by the Engi- neer. 07 -06 WORKMANSHIP All work shall be done by skilled craftsmen who are qualified to perform the required work and shall be done in a manner comparable to the best standards of practice found in the trade. All materials shall be evenly applied so as to be free from sags, runs, crawls, wrinkles, holidays, or any other ap- plication defects. All coats shall be of the pro- per consistency and properly brushed out so as to show the minimum of brush marks. All coats shall be thoroughly dry before the succeeding coat is ap- plied. All coats that are intended to hide shall be given another coat if the coating does not pro- perly hide the undercoat. 07 -07 PROTECTION OF WORK Full protection shall be given other work from damage by use of clean drop cloths during the time that the paint is being applied. 07 -08 MEASUREMENT AND PAYMENT No separate payment for work performed under this item.
